One of the most frustrating problems in a lot of houses is not enough hot water for everyone to take a shower. In mixer showers the hot water and the cold water are mixed so when hot water is used in another part of the house you get colder water and when hot water is used you get colder water. When you run out of hot water you have yo wait for the heater to heat more before you take a shower. Electric showers fix both of these problems because the water doesn't go through the heater but is heated by the shower. This works by heating a plate of metal with an electric current then the water passes through it heating the water. You can adjust the temperature with a thermostat dial so the water will stay the same temp throughout the whole shower.
